A road passes through a tunnel with a semielliptical cross section 64 ft wide and 18 ft high at the center. What is the height of the tallest vehicle that can pass through the tunnel at a point 22 ft from the center? See Fig. 21.70
The evaluation of the economics of pavement management decisions becomes a valuable tool in answering these questions: How much has it cost to deliver pavement functionality on the road network?
A plan view of a foundation with dimensions shown in the figure, has a uniformly distributed load of 300 lb/ft^2. Find the vertical pressure at point Z which is 7 ft below.
what is your recommendation for the maximum size of coarse aggregate for the following situation? a continuously
The joists from the previousquestion are supported by concrete beams that are 300mm wide by 500mm deep. The concretebeams span 8.4m. Assume the beam is also simply supported. The weight of the joistis 1.04 KN/m.
Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of
A 180 lb man and a 120 lb woman stand at opposite ends of a 300 lb boat, ready to dive, each with a 16 ft/s velocity relative to the boat. Determine the velocity of the boat after they have both dived
Estimate the velocity with which you would contact the ground if you jumped from an airplane at an altitude of 500ft and a) air resistance is negligible, b) air resistance is important, but you forgot your parachute, and c) you use a 25-ft-diameter p..
A gas mixture at 350 K and 300 kPa has the following volumetric analysis: 65 percent N2, 20 percent O2, and 15 percent CO2. Determine the mass fraction and partial pressure of each gas.
The beam is loaded with a concentrated live load of 10 kips at the center of its span, in addition to its own weight.. The dead load includes the beam weight. The steel is A242, Grade 50.
Design a 300 + sl m long variable graded terrace for a land having an average slope of 2 %. Maximum permissible velocity of water in the terrace channel is 60 cm/sec. The most sever rainfall expected in 10 yr RI has an intensity of 9 cm/hr.
Select reasonable pressures for the evaporator and the condenser, and explain why you chose those values.
A piston-cylinder device initially contains 20 g of saturated water vapor at 300 kPa. A resistance heater is operated within the cylinder with a current of 0.4 A from a 240 V source until the volume doubles.
